Analysis of maintenance and repair methods of imported bearings

Maintenance and inspection of imported bearings can ensure the reliability of operation, improve productivity and economy, prevent accidents, ensure the reliability of operation, improve productivity and economy, and ensure the bearing is in good condition for a long time. Maintain the original performance.

Cleaning of imported bearings: Gasoline and kerosene are commonly used as ordinary cleaning agents. When disassembling the lower bearing for inspection, first record the appearance of the imported bearing, confirm the residual amount of the lubricant, and start the washing of the bearing after sampling the lubricant for inspection. The cleaning is divided into coarse cleaning and fine cleaning, respectively, placed in the container, first placed on the bottom of the metal mesh, so that the imported bearings do not directly contact the dirt of the container.
1. Rough cleaning, use brush to remove grease and adhesive, and after it is almost clean, transfer to fine washing. If the imported bearing is rotated with dirt, it will damage the rolling surface of the imported bearing and should be noted.
2, fine fine washing, is to rotate the imported bearings in the cleaning oil while carefully cleaning. In addition, the cleaning oil should always be kept clean.

Inspection and judgment of imported bearings: In order to judge whether the removed imported bearings can be used, it is necessary to check after the imported bearings are cleaned.
The inspection contents include: monitoring the operating status, replenishing and replacing the lubricant, and checking the periodic disassembly. This is the standard of operation for maintaining the best mechanical operating conditions and is carried out regularly. As a maintenance item during operation, there are rotating sound, vibration, temperature, and lubricant status, and separate bearings such as tapered roller bearings can be inspected for the rolling surfaces of the rolling elements and the outer ring.
Check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase in the clearance of the imported bearing, and the damage abnormality with irrelevant dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring and horizontally rotate the outer ring to check if it is smooth.
Large imported bearings can not be rotated by hand. Pay attention to the appearance of rolling elements, raceway surfaces, cages, ribs, etc. The importance of imported bearings is more important and must be carefully checked.
In the use of imported bearings, we must regularly maintain and repair the bearings, so that the performance of imported bearings can be maintained, and the life of imported bearings can be extended.
